Abstract: An apparatus, comprising: a manikin with at least a head portion and an ear portion; wherein the head portion has an inner side and an outer side and accommodates a mouth simulator including an electro-acoustic transducer. Further, the apparatus comprises an electrodynamic vibrator with a vibrating rod wherein the vibrating rod is coupled to the manikin to exert a vibrating force at the head portion; and wherein the vibrating force induces vibration of the manikin at least at the ear portion. Thereby more realistic electroacoustic tests on devices under test such as such as headsets, headphones, earphones, hearing instruments and active hearing protectors can be performed.

Abstract: Disclosed is a headset for audio transmission. The headset is configured to be worn by a user. The headset comprises a speaker for sound transmission into the user's ear. The headset comprises a wireless communication unit for communication with an external device. The headset comprises a connection to a location-based service software, the location-based service software is configured for controlling at least one headset feature based on location data of the headset. The headset comprises a processing unit. The processing unit is configured for obtaining current location data of the headset. The processing unit is configured for enabling the location-based service software to detect if the current location data of the headset corresponds to a geographic region for which a first geo-fence is defined by the user. The processing unit is configured for changing the at least one headset feature, if a change criterion associated with the first geofence is satisfied; wherein the change of at least one headset feature is defined by the user.

Abstract: A method at a wearable electronic device with: a first electro-acoustic input transducer and a second electro-acoustic input transducer arranged to pick up a first acoustic signal and convert the first acoustic signal to a first microphone signal and second microphone signal; and a third electro-acoustic input transducer arranged to pick up a second acoustic signal and convert the second acoustic signal to a third microphone signal; and a processor (140). The method comprises: generating a beamformed signal based on the first microphone signal (x1) and the second microphone signal; estimating a first frequency value representing a fundamental frequency in one or more of: the first microphone signal, the second microphone signal and the third microphone signal; configuring a first filter with one or more passbands at one or more integer multiples of the first frequency value and one or more stop bands adjacent the one or more stop bands; and filtering, using the first filter, one or more of: the first microphone signal, the second microphone signal and the beamformed signal.

Abstract: A wireless hearing device system comprising a wireless hearing device and a charging base. The wireless hearing device comprises a first earphone, a connecting band extending from the first earphone, a rechargeable battery and band contacts arranged on the connecting band. The charging base comprises a band support with support contacts, whereby the hearing device can be docked in the base, such that band contacts are in electrical contact with the support contacts, whereby the rechargeable battery can be recharged. The connecting band and the band support are adapted to be engageable in a contact range (X), in which the connecting band and the band support can be displaced in relation to each other in the longitudinal direction of the connecting band. The band contacts and the support contacts are embodied to be in electrical contact with each other in any position within this contact range (X).

Abstract: A communication apparatus (1), such as a mobile phone, a tablet computer or a laptop computer, provides charging reminders to the user of a connected peripheral device (14), such as a headset. The charging reminders are provided in dependence on an auxiliary status signal (AS) received from the peripheral device (14) and on detected charging events (ME), wherein a main charging event (ME) comprises a charging or replacement of a main battery (2) that energizes the communication apparatus (1). The auxiliary status signal (AS) indicates an auxiliary energy level (AL) of an auxiliary battery (15) of the peripheral device (14). The communication apparatus (1) detects low-battery conditions (LC), based on the indicated auxiliary energy level (AL), and provides notification signals (NS) for a user interface (11) to notify the user of the detected low-battery conditions (LC) in response to the detected main charging events (ME).The communication apparatus (1) acts to notify the user to conveniently charge or replace the auxiliary battery (15) of the peripheral device (14) together with the main battery (2) and thus prevent that the auxiliary battery (15) becomes discharged in the interval before a subsequent charging or replacement of a main battery (2). The communication apparatus (1) may aid its user in reducing the number of times a peripheral device (14) becomes inoperable due to a discharge of the battery (15).

Abstract: Noise cancelling headsets and a method of improving audio sensitivity for a headset are disclosed. The headset comprises a speaker, a microphone unit comprising at least a first and a second microphone for picking up incoming sound and generating a first audio signal generated at least partly from the at least first microphone and a second audio signal being at least partly generated from the at least second microphone, a signal processor being configured to receive and analyze the first audio signal and the second audio signal to determine one or more equalization filter coefficients, an equalization filter configured to receive the second audio signal and the one or more equalization coefficients, and to equalize the second audio signal according to the determined one or more equalization filter coefficients to provide an output audio signal, wherein the one or more equalization filter coefficient are determined so as to approximate a power spectrum of the output audio signal to a power spectrum of the first audio signal.
